Taking a Vacation

in this lab we basically get the ideas about function and how to handle the functions with related to their arguments and how to get a result from. Moreover it consist of not only one function but more than 3 function and for the final answer we call the earlier functions, get the result from it and add it up.  We also need the basic ideas of conditional statements to approach the codes. The most important thing is to learn how to define a function, with their proper arguments and call the function whenever you need to do something with it.
